Thanks. For the record, on my system, the problem doesn't happen even if the two characters are displayed using different fonts: The component character(s) are displayed by these fonts (glyph codes): ℝ: uniscribe:-outline-Symbola-normal-normal-normal-serif-13-*-*-*-p-*-iso10646-1 (#x471) ≤: uniscribe:-outline-Courier New-normal-normal-normal-mono-13-*-*-*-c-*-iso8859-1 (#x94) Does anything change if you add --eval "(setq use-default-font-for-symbols nil)" to the Emacs command line, before the file name to visit? In my case, this still doesn't reproduce the problem, and the two characters still use 2 different fonts, although ≤ now uses a different font, not the one used by the default face.
